Why is the grass green?

Because grass & the leaves of other plants contain a chemical called chlorophyll which is used in photosynthesis. The chlorophyll stores the sun’s energy/light chemically and uses this to produce sugars and oxygen. Chlorophyll has a pigment which reflects the the green wavelength of light.

What are Problems in Diabetic Control?

Poor control and so-called brittle diabetes with recurrent ketoacidosis and hypoglycaemia may result from some causes. Diabetes and growth. In spite of comparison between identical twins discordant for diabetes expresses many loss of final height, children with diabetes can hope a normal adult stature. Modest pubertal put off is more frequent. What is more, marked  Full Article…

What are Arteries and Veins?

Arteries When the pressure of the blood rises as a result of systole, large arteries, such as the aorta, expand. When the blood pressure falls during diastole, they recoil just like a stretched rubber band. A smoother flow of blood via the smaller arteries and still smaller arterioles is produced by the aid of this  Full Article…

What is Insulin?

A majority of children are controlled on medium duration human insulins and a regimen of twice daily combined short. There is the selection of mixing the two insulins in the syringe, which permits for titration on the basis of blood glucose profiles, or of using premixed preparations. Moreover, they have the advantages of decreasing errors inherent  Full Article…

What are Capillaries?

Capillaries have the simplest structure to all the components of the cardiovascular system. They are just a single cell layer thick and approximately 1 mm long, and are little more than tubes. The whole body is permeated with a fine mesh of these capillaries. Actually, their combined length is on the order of 60,ooo miles.  Full Article…

What are Clinical Features and Aetiology of Diabetes?

Diabetes mellitus is the disorder due to insulin deficiency. This is the result of irreversible islet beta cell hurt in the majority of juvenile diabetics. Although diabetes is uncommon, the incidence increases so that up to sixteen years of age, two per one thousand are influenced. Children account for only four to six per cent  Full Article…

What are Principal Aspects of an Electrocardiogram (ECG)?

P wave Formed by stimulation of the SA node, the P wave is a small upward deflection that accompanies depolarization of the atrial fibers. The wave is followed by the actual contraction of the atria by a fraction of a second. During the expression of the P wave, the ventricles of the heart are in  Full Article…

What is Electrocardiogram?

Located on the skin over the heart, a pair of surface electrodes will record a repeating pattern pattern of electrical changes. The voltage measured between these 2 electrodes will change as action potentials spread via the conduction system from the atria to the ventricles. A “picture” of the electrical activity of the heart is offered  Full Article…

What is the Formation of Fibrin(Clotting Factors)?

A meshwork of insoluble protein fibers called fibrin strengthens the platelet plug, so that fibrin, platelets, and commonly trapped red blood cells that give the clot a red color are included by blood clots. A more effective and compact plug are produced by the contraction of the platelets in the process of clot retraction in  Full Article…

What is Rh Factor?

Rh factor, which refers to rhesus monkey and in which these antigens were first found, is another group of antigens discovered in most red blood cells.

An Instruction of Bone Tumours and its Treatment

The two commonest malignant bone tumours contains Ewing and osteosarcoma tumour. Local swelling, pain and occasional pathological fractures are clinical presentation. In the femur around the knee or in the proximal humerus of adolescents and young adults, osteosarcomas arise more frequently. Ewing tumours appear usually in flat bones of the axial skeleton, and the mid  Full Article…

What are Germ Cell Tumours and Renal Tumors?

Germ cell tumours Germ cell tumours arise from precursors of sperm and ova. However, they retain the potential to yield tissues resembling any somatic or in favor of structure. Besides that, germ cell tumours may be benign or malignant. They arise either within extra-gonadally or the gonades, where they are checked predominantly in the midline, consisting of  Full Article…

What is the Composition of Blood?

In the average adult, the total blood volume is almost 5 liters, composing 8 percent of the total body weight. Blood leaving the heart is referred to as arterial blood.

What are Pancreatic Islets (Islets of Langerhans)?

Two hormones including insulin and glucagon are secreted by the pancreatic islets. Both of them are critically connected with the regulation of blood glucose levels in the body. Hormones that regulate metabolism, digestion, immune function, and reproduction are secreted by numerous other glands. The pancreas is both an exocrine and an endocrine gland. The endocrine  Full Article…

What are Thyroid Hormones?

Obtained in the diet, iodine is essential for the synthesis of thyroxine. Iodine is normally contained by the commercial salt as an additive, and seafood is a source of iodine.

What is Chemical Classification of Hormones?

Secreted by different endocrine glands, hormones are various in their chemical structure. Whereas, all hormones can be grouped into 3 basic chemical categories: Catecholamines contain epinephrine and norepinephrine; Polypeptides and glycoproteins contain shorter chain polypeptides, just like antidiuretic hormone and insulin; and thyroid-stimulating hormone is the large glycoprotein. Lipophilic hormones (those that are lipid) contain steroids,  Full Article…
